A winze is a minor connection between different levels in a mine. When worked upwards from a lower level it is usually called a raise; when sunk downward from a higher level it may be called a sump. The top of a winze is located underground and it is not equipped with winding gear.

In mining: Vertical openings: shafts and raises …level downward is called a winze; this is an internal shaft. Read More

A vertical opening driven downward connecting two levels in a mine. When one is standing at the top of a completed connection the opening is referred to as a winze, while when standing at the bottom, the opening is a raise, or rise. Synonym of: winds ii. A subsidiary shaft that starts underground. It is usually a connection between two levels.

2018年3月14日 · This document discusses various techniques for raising, which is the vertical or steeply inclined excavation that connects different levels in underground mines.

winze A winze is like a shaft that starts undergound. They are much less common than raises, but they are really cool. Often the top of a winze has a good sized station that once held (or still holds) hoisting equipment, and enough room to transfer material from hoist buckets to ore cars.

There are drill patterns and charge designs used to create these initial voids in the production cycle. This paper discusses common slot or winze designs for production drilling and blasting; and various critical design criteria for these.

2023年3月7日 · Effective mining in bulk underground mining is largely reliant on the recovery of the initial void created by drilling and blasting. These initial voids are known by various names such as the long hole rise, slot, or winze of the stope.

Two separate, however similar definitions of a winze are provided below: - “A winze is a vertical or inclined underground opening that is driven downward from one level to another level or from surface to a level”. Underground Mining Methods Handbook, W A Hustrulid, 1982.
